i running out of time project. please help.

i resolved issue using absolute path of image beingness read method "imread". because web project, not taking relative path of default project folder.

i doing:

highgui.imread("img_perspective.png", highgui.cv_load_image_grayscale);

i changed to:

highgui.imread("c:/users/imagepreprocessing/webcontent/web-inf/img_perspective.png", highgui.cv_load_image_grayscale);

hope helps.
